Siyao Meng updated HDDS-6857:
-----------------------------
Description:
Snapshot delete through a Ratis transaction.
The Ratis tx moves the snapshot from ACTIVE state to DELETED.
This does not remove the snapshot's RocksDB checkpoint directory. That would be
done by a new background service {{SnapshotDeletingTask}}, which would also
move the snapshot to RECLAIMED state and eventually remove the snapshotInfo
from the table and remove the snapshot DB checkpoint.
was:
This Jira can be used to track all the tasks associated with Deleting a
Snapshot.
Snapshot Delete would also be driven through a RATIS transaction.
This API should move Snapshot from Active State to Deleted State. We should not
remove the Snapshot RocksDB checkpoint directory yet.
There will be another background thread that should reclaim all the keys that
will go orphan as part of Snapshot deletion.
The Snapshot should move to a deleted-and-reclaimed state only after all such
would-be-orphan keys and their data blocks are deleted.
The design doc has details on how to identify would-be-orphan key-set when the
snapshot gets deleted.
